Technical field
The utility model is related to roll control systems technology field, more particularly to a kind of non-gap rolling system is applied to
The continuous rollings production line such as bar, angle steel, wire rod.
Background technology
Hot-rolled steel production line generally comprises roughing mills, intermediate mill, mm finishing mill unit, continuous during conventionally produced
2 steel billets when entering roughing mills head rolling mills, the time interval of minimum 2S need to be kept, to ensure that production is smoothed out.
Under traditional handicraft control, continuous 2 steel billets cancel the time interval of 2S, and gapless can lead to technique thing below into steel
Therefore:
(1) the 1# flying shears segmentation in roughing mills is unclear;Due to hypotelorism between steel billet, 1# flying shear (flying shears can be caused
Main function:Rolled piece in lateral shear movement, cropping, back-end crop, scale) head or tail portion that steel billet can not be differentiated, it can not
It is cut off, back-end crop operation, finished product can be caused unqualified.
(2) rolled piece can be caused to pierce inside kink, occurs knocking into the back, the technology accidents such as piling of steel:Due to steel billet join end to end into
Enter milling train, every two steel billets hypotelorism in milling train can be caused, when the action that conforms to a conventional pattern of rising of kink has not been completed, next steel
Base will be with coming in, it may appear that technology accident occurs in drill bushing situation, if frequently occurred, can substantially reduce operating rate, reduce production
Amount.
(3) if traditional handicraft during the rolling process, if steel billet joins end to end into milling train, does not go out in order to prevent
The head of existing 1# flying shear None- identified rolled pieces, tail portion;It prevents and pierces inside kink, be exactly generally that steel is drawn to roll by the way of
System draws steel rolling that material type and product quality can be caused to cannot be guaranteed, and minus tolerance is unstable, and accident rate is high.
So the utility model has developed a kind of gapless control system, gapless switch board is set, independently of former rolling line
Switch board participates in former roll line control cabinet further through live tracing detection element.
